A Series

Single & Two Stage, Pressure Lubricated (5-40 HP) Reciprocating Air Compressor

The A-series reputation has been built on reliability, quality, and accessibility to all components. Products include air-cooled bare compressors, boosters, and vacuum pumps. A-Series compressors include counterbalanced crankshaft to ensure smooth operation, heavy-duty cast iron construction, and deep-finned cylinders and heads, which quickly dissipate the heat of compression. Superior lubrication is accomplished through a gear driven positive displacement oil pump powered by the crankshaft. A-series bares and boosters are ideal for petroleum refineries, oil rigs, ore mines, plant air and vacuum, engine starting and well head servicing.
